Asset Vaults	Stablecoin and RWA supply, utilization, lender shares and debt accounting
Risk Engine	Initial, maintenance and carry factors; caps; concentration; market states
Oracle Router	Prices, freshness, sequencer status, issuer/token pauses and session data
Execution Router	RFQ routing, partial liquidations, RWA buy-ins and approved fallbacks
Asset Registry	Canonical contracts, issuer metadata, price feeds, multipliers and eligibility
Backstop / Reserve	Direction-specific loss accounting and reserves

One control plane. Two financing books.
